PTRS has developed depreciation schedules which estimates the decline of the subject’s value over time. This provides our customers with Fair Market Value (FMV) that is credible based on methodology developed by the American Society of Appraisers and the IAAO. Nearly, all equipment depreciation tables used today are based on survival studies (eg. Marshall & Swift) and do not account for obsolescence found in equipment. PTRS Depreciation Schedules are based on economic useful life, which estimates all forms of deprecation found in any equipment type (physical, functional, and economic). An asset’s economic life gives our customers a true FMV or a creditable value, according to Uniform Standards of Professional Appraisal Practices (USPAP).
